Solar street light common troubleshooting methods ( A)
common troubleshooting methods (solar street lamps 2)
1, the whole light not on. Used for outdoor lighting, solar street lamps are often faced with high temperature and rainy, cold rain and snow weather, and solar street lamps controller is usually installed inside a light pole, short-circuit phenomenon easy to cause the water to the controller. First to observe whether there is water rust is the terminal of the controller, if a controller is damaged, most likely no battery voltage measurement, such as the 12 v power supply system, solar street lamps battery voltage is lower than 10. 8 v battery has no battery, need more change. Check folding panels under normal working day if there is a voltage, electric current output. Not just panel is damaged, replace the panels. The above are no problem, you should check the light source, only through to the light source power, to see if light, no light, replace the light source. 2, solar street lamps flickering lamp holder. Of the cause of the fault, the line contact, electric, battery capacity serious decline, in the case of line no problem, replace the battery. 3, light time is short, short duration of rainy day. Usually battery storage capacity fell, the battery sufficient cause. Replace the reasonable storage battery.
